Our Process
Free In-Home Assessment
We evaluate the existing tub, plumbing configuration, and surrounding tile to plan the most efficient conversion approach.
Tub Removal
The existing bathtub and surrounding tile are carefully removed. Plumbing is reconfigured as needed for the new shower layout.
Waterproofing & Shower Pan
A properly sloped shower pan is installed and all surfaces are waterproofed to prevent moisture intrusion behind the tile.
Tile Installation
Shower walls and floor are tiled to your specifications, with built-in niches and bench seating installed as desired.
Glass & Fixtures
Frameless glass enclosure, showerhead, controls, and accessories are installed to complete the transformation.
How long does a tub-to-shower conversion take in Nassau County, Queens, or Brooklyn?
Most tub-to-shower conversions with General Modernizer are completed in 2 to 3 days. This includes removing the existing bathtub, installing the new shower pan and waterproofing, tiling the walls and floor, and installing the glass enclosure and fixtures. In Queens co-op apartments where work hours are restricted by the building, the timeline may extend to 3 to 4 days. We provide a precise written timeline during your free in-home consultation.
How much does a tub-to-shower conversion cost in Nassau County?
Tub-to-shower conversions in Nassau County typically cost between $4,000 and $12,000. A standard conversion with a prefabricated shower base, subway tile walls, and a basic glass door averages $4,000 to $6,000. A mid-range conversion with a custom tile shower floor, large-format wall tile, and a frameless glass enclosure typically runs $6,000 to $9,000. A premium conversion with natural stone tile, a built-in bench, and designer fixtures ranges from $9,000 to $12,000.
Do I need a permit for a tub-to-shower conversion in Nassau County?
In Nassau County, a tub-to-shower conversion that uses the existing plumbing drain location and does not relocate supply lines typically does not require a permit. If the conversion involves moving the drain, adding new supply lines, or making any structural changes, a permit is required. In Queens co-op buildings, board approval is required before any work begins regardless of permit status. General Modernizer handles all permit applications and co-op board documentation as part of our full-service process.

General Modernizer assesses your existing plumbing, tile, and floor structure during the free in-home consultation to confirm the best conversion approach for your specific bathroom.

How much does a tub-to-shower conversion cost?+
Tub-to-shower conversions with General Modernizer in Nassau County typically range from $4,000 to $12,000 depending on the size of the space, the tile selection, and whether a frameless glass enclosure is included. A basic conversion with standard subway tile and a semi-frameless door starts around $4,000 to $6,000.

Will removing my bathtub hurt my home's resale value?+
In most cases, removing a bathtub does not hurt resale value, and in many Nassau County homes it actually increases it. Walk-in showers are among the most requested features by today's homebuyers. Real estate data consistently shows that homes with at least one bathtub remaining and a walk-in shower in the master bathroom sell faster and for more money than homes with only tubs. If your home has two or more bathrooms, converting one tub to a walk-in shower is generally a smart investment. We can discuss the best approach for your specific home during your free consultation. Call (516) 212-7195.
Can I add a bench or niche to my new shower?+
Absolutely. Built-in shower benches and recessed tile niches are popular additions that General Modernizer installs as part of the conversion process at no extra disruption to the project timeline. A bench can be tiled to match the shower walls for a seamless, custom look, and provides a comfortable seat for shaving or bathing. Recessed niches are built directly into the shower wall and provide convenient storage for shampoo, conditioner, and soap without protruding into the shower space. Both features add significant visual appeal and practical value. Call (516) 212-7195 to discuss your design options.
